ills, in the county of Derby, England, and 44 Hall street, New Mills aforesaid, have invented new and useful Improvements in or Connected with Beetling-Machines, of which the ollowing is a specification.

Our said invention relates to improvements in or connected with pneumatic beetling machines, that is, to beetles wherein the ammersare separately or otherwise actu- The pneumatic hammer ated by air pressure.

This arrangement is however a somewhat complicatedand expensive construction and the incidental combination gles to and in line with the vertical axis of the pneumatic hammer cylinders, so that, a most compact and simple arrangement is obtained.

greatly varied as is obvious, the mechanism sleeve or cylinder 3 which cylinder 3 is bolted to thegirder or beam and so held in place. Each cylinder 3 is prepared with an air channel 3 and fitted with a slidable being by way of example.

We may fit guards such as 18 or we may incase the parts below the girders or beams hammer 1 to which a beetling block 5 1S 2 so as to keep said parts clear of dirt, fluff, fixed in suitable manner. A back pressure or such like, and to prevent oil or grease beor other valve 6 is fitted with respect to the ing thrown up onto the beetled goods. Also, fixed sleeve or cylinder 3 and such may be a we may, instead ofarranging the pneumatic spring pressed ball valve 6. Fitting around heads vertically, dispose some or all of the the fixed sleeve or cylinder 3, already heads obliquely but so that the center line named, is an outside sliding cylinder 7 of such beetle heads if continued would strike the center line of the beam.

The up and down movement of each outside sliding cylinder may be brought about by any other mechanical actuating device or gear other is obvious, and we wish to reserve the right in respect of equivalent devices for effecting the mere reciprocation of the outside sliding cylinder.

We may combine'a' cushioning device and also means to put any back-pressure valve and consequently beetle head out of action, as known. The drawings illustrate a form of pivoted lever 19 for this latter purpose, the lever being capable of occupying either of two positions in one of which positions as shown in full lines the ball valve 6 is which is moved up and down and is guided by the fixed sleeve or cylinder 3. On the downward movement of said outside sliding cylinder, air is drawn in past the backpressure valve 6, down the air channel 3 and the outside sliding cylinder 7 is charged with air throughout its entire downward stroke. The slidable hammer 4t carrying the block also falls simultaneously due to gravity and air suction. Upon the return movement of said outside sliding cylinder the air or back pressure valve 6 closes automatically and the air is compressed, the hammer actuated, and the blow from the beetle block delivered.

The outside liding cylinder 7 has preferably formed therewith an elongated slot or stirrup 8, or is otherwise fashioned to suit pushed off its seat against the actionof the the longitudinal shaft 9, and, on this shaft, spring thereby stopping the hammen In and in the slot or stirrup is fixed an eccenthe other position the spring closes the ball trio 1() by means of a set screw 10*.

The part marked 20 is a screwed plug or air cushion plug having a small channel 2O by the covering of which a small quantity of air is trapped on the descent of the slidable hammer plunger 4; (enlarged at 4".) such parts serving as a cushioning device.

that what we claim is:

We declare machine a lower movable cylinder,

preferred arrangement which is illustrated, a separate eccentric block 10 is fitted in respect of each outside sliding cylinder 7 (see Fig. 2) each such eccentric engaging the top and bottom of the slot or stirrup 8 or parts attached thereto to effect the desired up and down movement. Such eccentrics can be driven at a high speed so that the sliding cylinder reciprocate smoothly and due to the eccentric peripheries being constantly in touch with the top and bottom faces of the slots or stirrups 8 at all positions in the revolution.

WVith the construction above indicated, drive the two lines of neumatic heads and thus all the mechanism incidental to driving is as compact as possible. The shafts 9 are supported at close intervals by suitable self-oiling or other pedestals carried on the bed-plates 21.

In the system of driving shown, in respect of the two shafts 9, 9 the main shaft 11 drives by a strap or otherwise the pulley 12 and consequently the shaft 9* is rotated. On this shaft or on a clutch boss a chain wheel 13 is fixed which, through a chain 14: (preferably a silent chain) drives the chain wheel 15 on the shaft 9 Clutches 16, 17, and actuating gear therefor, are fitted so that either actuating shaft 9, 9 can be actuated or stopped at will. The driving arrangements for thesliding cylinders may be 1. In a pneumatic beetling a fixedcylinder, a

sliding hammer support inside said fixed cylinder, a hammer on said support to act against a beam the movable cylinder charg ing the fixed cylinder during its downward stroke and actuating the sliding hammer support on its return stroke to drive the hammer upward to the beam, the sliding hammer support falling by gravity assisted by air suction as set forth.

2. In a pneumatic beetling machine a fixed cylinder, a slidinghammer support mounted therein, a hammer on said support, and an outside movable cylinder sliding on said fixed cylinder, a stirrup device on said outside movable cylinder, an eccentric engagin said stirrup and a shaft for the eccentric sai eccentricbeing in constant contact with the stirrup at all positions during revolution as described.

8. In a pneuma ticbeetling machine a as illustrated merely indicating one plan and than by eccentrics or cams as p drive said shaft, the sliding hammer support falling due to gravity and air suction and beingactuated to strike the blow on the ascent of the outside movable cylinder as described.

4. A pneumatic beetling device comprising an over-head cloth beam, a fixed cylinder, an air valve carried thereby, a sliding support therein, a hammer on said support, an outside movable cylinder, a stirrup connected thereto, an eccentric engaging the stirrup,

said eccentric, all arranged below the cloth beam, and means to drive the shaft carrying the eccentric.

5. A pneumatic beetling machine comprising a number of beetling heads with overhead cloth beam, each beetling head comprising a fixed cylinder, supporting means therefor, a sliding supportin each cylinder, a hammer on each support, an outside movable cylinder for each head, an attached stirrup for each movable cylinder, eccentrics for each larly,
